Formulation of an Environmentally Safe Oil Based Drilling Fluid

SPE Asia-Pacific Conference, 1991
Abstract The usage of oil especially diesel oil as the continuous phase of drilling mud is widespread when drilling through sensitive producing formation and troublesome shale zone. Diesel oil is harmful to the environment-particularly marine environment in offshore application due to extensive legislation now exist in ...

Development of Organoclays for Use in Oil-Based Drilling Fluids

Materials Science Forum, 2012
The organoclays are derived from bentonite clays treated in aqueous solution with surfactants, which are incorporated into the interlayer surface of clays, covering them with an organic layer; so, the naturally hydrophilic clay becomes hydrophobic.

Environmentally Safe Oil-Based Fluids for Drilling Activities

Proceedings of SPE/EPA Exploration and Production Environmental Conference, 1999
Abstract Diesel based drilling fluids had been widely used in the past due to its low price in the market. However, it has been well documented the adverse health and environmental effects of Diesel mostly due to the high aromatic hydrocarbon content which makes it toxic.

Wettability Alteration Induced by Oil-Based Drilling Fluid

Proceedings of SPE Formation Damage Control Symposium, 1988
ABSTRACT Invert emulsion oil based drilling fluids rely on surfactants and emulsifiers to maintain the stability of the invert emulsion. An excess of oil wetting agents in the system is usually necessary in order to oil wet the drilled solids. This excess of surfactants causes wettability alteration in the drilled formation.

Synthesis of superamphiphobic nanofluid as a multi-functional additive in oil-based drilling fluid, especially the stabilization performance on the water/oil interface

, 2020
Nanofluids, as an effect additive in oilfield chemistry, has recently attracted significant attention. In this study, the superamphiphobic nanofluid (SAN) was synthesized to be a multi-functional additive in oil based drilling fluid (OBMs).

The Effect of Oxidation on Viscosity of Oil-Based Drilling Fluids

Journal of Canadian Petroleum Technology, 2006
Abstract True downhole rheological properties affect equivalent circulating density, hole cleaning, barite sag, surge/swab pressures during tripping, pump pressure, and bit hydraulics. Gelation and excessive viscosity are major concerns at high temperatures.

Separation and Recycling of Used Oil-Based Drilling Fluids

IPTC 2009: International Petroleum Technology Conference, 2009
Abstract A novel approach has been taken to separating, recovering and recycling the oil-continuous phase from used oil-based drilling fluids. The method is based on destabilizing and aggregating the suspended solids and brine droplets through the application of polymers and surfactants in a controlled mixing device.
